I know of two ways to trap keypresses.  Both require XCMDs.  The first is an
XFCN called InKey that will return any pending keypressed when called.  You put
it in an idle loop.  It works ok if the user doesn't type too fast.

The other is an XCMD called ControlLock that makes the Mac think the Control
key is locked (even on keyboards with no Control key), thus generating a
controlKey message on every keypress.  (I prefer this one, as you get a message
generated for every keypress and never lose any.)

These are both short, and have both been posted to this newsgroup.  If enough
people clamor, I can repost them.
